Mass spectrometry of carbon nitride C3N4

Mechanistic Insights into the Synthesis of Platinum–Rare Earth Metal Nanoalloys by a Solid-State Chemical Route

“…When the temperature increased to 550 °C and above, a significant amount of C + , C 2 H 2 + , C 4 H 4 + , CN + , and C 2 N 2 + was detected, which are the typical fragment ions from the decomposition of polymeric carbon nitride. 35 A decomposition temperature of about 550 °C is also consistent with that reported in the literature. 33 3.1.3.…”

“…As the temperature was increased from room temperature to 500 °C, only a small amount of CH 3 + or NH + ( m / z = 15) and C 2 H 6 + ( m / z = 30) was detected at around 200 °C and 500 °C, corresponding to hydrocarbon or NH 3 . When the temperature increased to 550 °C and above, a significant amount of C + , C 2 H 2 + , C 4 H 4 + , CN + , and C 2 N 2 + was detected, which are the typical fragment ions from the decomposition of polymeric carbon nitride . A decomposition temperature of about 550 °C is also consistent with that reported in the literature …”

Investigation of the structure of carbon-nitrogen compounds

“…It should be emphasized that the mass spectrometric technique used in the present work makes it possible to record 10 mass spectrometric lines simultaneously in contrast to our previous study [12]. Observing the behavior of the intensities of these lines in the mass spectrum during heating of the sample, we can judge the thermal stability of the 2D-3D network (Fig.…”

“…The IR spectra were recorded on an FSM-1201 IR Fourier spectrometer. In this work, the investigations were also performed with a modified MSKh-6 mass reflectron equipped with a thermal destructor and an ion source with electron impact ionization ( E = 75 eV) [12].…”

A new chemical compound with an unusual ratio of number of carbon and nitrogen atoms – C(N12): quantum-chemical modelling

“…[19][20][21][22][23][24] Tricarbon tetranitride or simply carbon nitride C 3 N 4 , rst described 100 years ago in ref. 25 and considered in more detail in a number of other works, in particular [26][27][28][29][30][31][32] and review articles, [33][34][35][36] stands apart from this background. The carbon-: nitrogen ratio in these compounds varies from 69 : 1 in diheterofullerene (C 69 N) 2 to 1 : 12 in tetraazidomethane C(N 3 ) 4 .…”
